Wishful thinkin' indeed, since that "foreshadow" wasn't one at all. Just a bunch'a junk 'bout how N knows he's still boundless work t' do to achieve his goals. Wasn't any more of a hint that he'd be in newer games than BW1's ending.
It definitely gives canon leave for 'em to appear in non-Unova regions, but I'm just sayin' I doubt it alludes to anythin' specific. Not that I'd complain if I'm wrong.
Wrong. I said possible foreshadowing. If N actually does end up becoming a bridge of some sort, then that quote would have been foreshadowing. If he doesn't, then it wasn't foreshadowing.
